Helm chart
This reference is generated from the Tetragon Helm chart values.
The Tetragon Helm chart source is available under github.io/cilium/tetragon/install/kubernetes/tetragon and is distributed from the Cilium helm charts repository helm.cilium.io.
To deploy Tetragon using this Helm chart you can run the following commands:
helm repo add cilium https://helm.cilium.io
helm repo update
helm install tetragon cilium/tetragon -n kube-system
To use the values available, with helm install or helm upgrade, use --set key=value.
Values
| Key | Type | Default | Description |
|---|---|---|---|
| affinity | object | {} | |
| crds.installMethod | string | "operator" | Method for installing CRDs. Supported values are: “operator”, “helm” and “none”. The “operator” method allows for fine-grained control over which CRDs are installed and by default doesn’t perform CRD downgrades. These can be configured in tetragonOperator section. The “helm” method always installs all CRDs for the chart version. |

For more control, you can select which binary or binaries should have their arguments redacted with the binary_regex field. NOTE: This feature uses RE2 as its regular expression library. Make sure that you follow RE2 regular expression guidelines as you may observe unexpected results otherwise. More information on RE2 syntax can be found here. NOTE: When writing regular expressions in JSON, it is important to escape backslash characters. For instance \Wpasswd\W? would be written as {"redact": "\\Wpasswd\\W?"}. As a concrete example, the following will redact all passwords passed to processes with the “–password” argument: {“redact”: ["–password(?:\s+ |
